## 'Ultra Light Hat KIDS' Launches in Stores
Marufuku Sen-i Co., Ltd. (Headquarters: Nishio City, Aichi Prefecture; Representative: Tomoyuki Murase), a manufacturer specializing in UV and heat protection products for 70 years, has released its highly anticipated 'Ultra Light Hat KIDS.' Following strong customer demand from users of the adult 'Ultra Light Hat' series—which consistently sells out—the kids' model is now available for purchase at Hands stores nationwide (excluding some locations).
This kids' version was created in response to concerns from parents about summer heat for their children. It offers a solution for the increasingly extreme summers, with the Japan Meteorological Agency defining days with temperatures over 40°C as 'extreme heat days' and 2025 noted as having one of the hottest summers on record.
Retaining the high functionality of the adult version, the kids' hat features the proprietary 'ShaBō Aluminum Cool Tech,' which keeps the inside temperature approximately 10°C cooler, even under direct sunlight. Designed for children who struggle to regulate their body temperature, it reduces heatstroke risks while maintaining a lightweight, breathable design for comfort during sweaty seasons. It also provides a gentle fit, UV protection with 99% shading rate, and durable, machine-washable fabric.
## Key Features of Ultra Light Hat KIDS
- UV Protection: With a 99.9% UV cut rate and 98% shading rate, it protects children's delicate skin from UV damage.
- 'ShaBō Aluminum Cool Tech': A three-layer structure using high-insulation, high-breathability material that keeps the temperature inside the hat over 10°C cooler according to tests conducted at the Nagoya Industrial Research Institute.
- Outdoor-ready design: Includes a water-repellent brim for light rain and a drawcord to prevent it from blowing off in the wind.
- Easy Care: Machine washable when placed in a laundry net.
